[0002] With the improvement of user requirements for audio and video experience, audio output quality has become an important indicator for measuring the performance of terminal devices.

[0003] In a terminal device, for example, a television, its sound box assembly is usually integrally arranged with the television and arranged in a fixed orientation, which makes the sound radiation direction of the sound box fixed and lacks adjustment capability.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0074] As shown in Figures 1 to 6 The sound box device 100 includes a sound box assembly 120, a rotating drive mechanism 140, and a controller (not shown in the figure), the sound box assembly 120 can move between a non-working position and a working position, in the case of the sound box device 100 being installed in the terminal device body 200, the non-working position is a spatial position in which the sound box assembly 120 is at least partially accommodated inside the terminal device body 200, and the working position is a spatial position in which the sound box assembly 120 is at least partially moved out to the outside of the terminal device body 200.

[0075] The sound box device 100 can be installed in the terminal device body, and the terminal device to which the terminal device body belongs can include but is not limited to: television equipment (such as ultra-thin television), all-in-one machine, mobile terminal or home theater system, etc. Electronic equipment that needs to integrate audio output function. For example, the terminal device body is the television body of the television equipment. The television body includes but is not limited to: screen, main control board, power module, shell, etc.

[0076] Exemplarily, the sound box assembly 120 can include a loudspeaker for converting electrical signals into sound and radiating. For example, the sound box assembly 120 can contain different types of loudspeakers such as full-frequency loudspeaker units, bass units (such as subwoofers) or treble units to cover different audio frequency bands.

[0077] Exemplarily, after the sound box assembly 120 moves out of the terminal device body, the sound radiation direction of the sound box assembly 120 is by default towards the front of the screen of the terminal device.

[0078] The non-working position is a preset initial position of the sound box assembly 120 inside the terminal device body 200, and the working position is a preset target position of the sound box assembly 120 moving out of the terminal device body.

[0079] For example, when the sound box assembly is in the non-working position, the sound box assembly is completely accommodated in the frame structure of the terminal device body, achieving the hiding of the sound box assembly; when the sound box assembly moves to the working position, the sound box assembly completely extends out of the terminal device body, so as to provide a movement space for the rotating movement of the sound box assembly.

[0080] For example, the non-working position can be preset inside the side frame of the terminal device body, and the working position corresponds to outside the side frame of the terminal device body; in this arrangement, the sound box assembly slides out of the side frame of the terminal device body in a direction parallel to the screen plane of the terminal device. For example, the non-working position can be preset inside the bottom frame of the terminal device body, and the working position corresponds to outside the bottom frame of the terminal device body; in this arrangement, the sound box assembly extends downward from the bottom frame of the terminal device body.

[0081] During the movement of the sound box assembly 120 between the non-working position and the working position, the loudspeaker unit of the sound box assembly 120 remains fixed in the direction, and after the sound box assembly extends out of the terminal device body, the loudspeaker unit of the sound box assembly is towards the front of the screen of the terminal device, so that after the sound box assembly moves out of the terminal device body, the sound radiation direction thereof is directly towards the front of the device screen. Thus, without rotating the sound box assembly, the natural alignment of the sound radiation direction and the screen display direction can be achieved, forming an initial sound field facing the front of the device screen area.

[0082] In some examples, the sound box assembly 120 can move between the non-working position and the working position through a linear sliding mechanism. For example, the linear sliding mechanism can include a guide slide rail fixedly installed inside the terminal device body and a sliding block provided on the sound box assembly and matched with the guide slide rail. The slide rail can be arranged parallel to the long side of the device, and when the sound box assembly needs to sound, the motor can be controlled by the controller to drive the sound box assembly to linearly slide along the slide rail from the non-working position inside the terminal device body to the working position outside the terminal device body, so that the loudspeaker unit of the sound box assembly is at least partially exposed outside the terminal device body.

[0083] When the speaker assembly is in the non-working position, it is at least partially contained inside the terminal device body. At this time, the speaker assembly does not occupy external space, which is conducive to maintaining a light and thin appearance of the terminal device; when the speaker assembly is in the working position, it is at least partially moved out to the outside of the terminal device body, thereby realizing the telescopic movement of the TV, so that the speaker assembly can obtain a larger acoustic space after extending out of the terminal device body, thereby obtaining better sound effects.

[0084] The rotation drive mechanism 140 is in transmission connection with the speaker assembly 120 and is used to drive the speaker assembly 120 in the working position to rotate so as to change the sound radiation direction of the speaker assembly 120 .

[0085] The speaker assembly 120 can rotate relative to the terminal device body around a rotation axis, and the rotation axis is parallel to the length direction of the speaker assembly 120 and perpendicular to the thickness direction of the terminal device body. The thickness direction of the terminal device body is the direction from the front of the terminal device body screen to the back of the terminal device body.

[0086] Controller( Figures 1 to 6 The controller (not shown) is electrically connected to the rotation drive mechanism 140 and is used to control the operation of the rotation drive mechanism 140. The controller controls the rotation drive mechanism to generate a rotational force by sending a rotation control signal to the rotation drive mechanism 140, thereby driving the speaker assembly 120 that is transmission-connected to the rotation drive mechanism 140 to rotate. When the speaker assembly 120 rotates, the sound radiation direction of the speaker assembly 120 changes accordingly, thereby achieving dynamic adjustment of the sound direction, thereby solving the problem of limited terminal sound effects caused by the fixed sound radiation direction of the front-sound speaker structure used in terminal devices (such as TVs).

[0087] For example, the rotation angle range of the speaker assembly driven by the rotary drive mechanism 140 can be set according to actual application needs, for example, the rotation angle range can be set to -45° to 45°. The minimum angle change supported by the rotary drive mechanism can be a preset angle between 0.5° and 2° to achieve fine adjustment of the sound radiation direction.

[0088] In some examples, the controller can control the rotation drive mechanism to drive the speaker assembly to rotate according to the user's current position or the user's remote control command, so as to change the sound radiation direction of the speaker assembly 120.

[0089] For example, the controller can be used to generate a target rotation angle based on the user's current position information (for example, the user is a TV viewer), and generate a rotation control signal based on the target rotation angle, and send the rotation control signal to the rotation drive mechanism 140 to drive the speaker assembly 120 in the working position to rotate from the initial angle to the target rotation angle, so that the speaker assembly 120 in the working position is facing the user's current position.

[0090] Here, the initial angle may refer to the reference direction directly in front of the terminal device body, and the target rotation angle indicates the angle to which the speaker assembly needs to be rotated toward the user's current position.

[0091] Here, the user's current location information can be detected by a location sensor, which can be an infrared detector.

[0092] In some examples, the controller may include a microcontroller unit (MCU). Of course, the controller may also include other devices that can have control functions.

[0093] In some examples, the speaker device may include multiple speaker assemblies, and the multiple speaker assemblies may be respectively arranged in different border areas of the terminal device body. For example, the multiple speaker assemblies are respectively arranged on the left border, right border and / or bottom border of the terminal device body.

[0094] Taking a television as an example, it can be provided with multiple speaker assemblies, for example, a pair of speaker assemblies are respectively provided on the left and right frames of the television body, and a speaker assembly is provided on the bottom frame of the television body.

[0095] Each speaker assembly can independently move from a non-working position inside the terminal device body to a working position outside the terminal device body, and after reaching the working position, the sound radiation direction can be adjusted through the respective connected rotation drive mechanisms.

[0096] When the speaker device includes multiple speaker components, the controller can coordinate the telescopic movement and rotational movement of the multiple speaker components. For example, it can simultaneously control the speaker components arranged on the two side frames and the bottom frame of the terminal device body to move from the non-working position inside the terminal device body to the working position outside the terminal device body, and support the independent rotation of each speaker component to achieve dynamic construction of a multi-channel sound field.

[0097] For example, when multiple users are located in different listening areas of the TV, the controller can generate a target rotation angle adapted to each speaker assembly based on the position information of each user, and drive it to rotate in the direction of the corresponding listening area. For example, when the first user is located in the left sofa area and the second user is located in the right seat area, the controller controls the first rotary drive mechanism to drive the first speaker assembly (disposed on the left frame of the TV body) connected to it to rotate left to cover the left listening area; at the same time, the controller controls the second rotary drive mechanism to drive the second speaker assembly (disposed on the right frame of the TV) connected to it to rotate right to cover the right listening area. The speaker assembly on the bottom frame of the TV can maintain the front sound output. In this way, personalized adjustment of the sound field in a multi-user scenario can be achieved.

[0098] Compared with the sound box fixedly arranged on the terminal device, the sound box device provided in the embodiment comprises a sound box assembly capable of moving between a non-working position and a working position. When the sound box assembly is in the non-working position, the sound box assembly is at least partially accommodated in the terminal device body. When the sound box assembly is in the working position, the sound box assembly is at least partially moved out of the terminal device body. In this way, when the sound box needs to sound, the sound box assembly can be moved from the terminal device body to the outside of the terminal device body, so that the terminal device body can effectively expand the sound radiation space while maintaining the light and thin appearance. Moreover, the controller controls the rotating driving mechanism to drive the sound box assembly in the working position to rotate, so that the sound radiation direction of the sound box assembly can be dynamically adjusted, thereby improving the flexibility of sound field pointing and achieving better sound effect of the terminal device.

[0099] In one embodiment, as shown in Figure 3 and Figure 4 The sound box device can further comprise a moving driving mechanism 110. The moving driving mechanism 110 is in transmission connection with the sound box assembly 120 and is used to drive the sound box assembly 120 to move between the non-working position and the working position. When the moving driving mechanism 110 works, the sound box assembly 120 can be driven to move out of the terminal device body to the outside of the terminal device body or to be driven to be moved back from the outside of the terminal device body to the inside of the terminal device body.

[0100] The controller is in electrical connection with the moving driving mechanism 110. When the controller controls the moving driving mechanism 110 to drive the sound box assembly 120 to move, the controller prohibits the rotating driving mechanism 140 from driving the sound box assembly 120 to rotate. When the controller controls the rotating driving mechanism 140 to drive the sound box assembly 120 to rotate, the controller prohibits the moving driving mechanism 110 from driving the sound box assembly 120 to move.

[0101] For example, when the controller needs to control the moving driving mechanism 110 to drive the sound box assembly 120 to move, the controller only sends a moving control signal to the moving driving mechanism 110 and does not output a rotating control signal. When the controller needs to control the rotating driving mechanism 140 to drive the sound box assembly 120 to rotate, the controller only sends a rotating control signal to the rotating driving mechanism 140 and does not output a moving control signal.

[0102] In some examples, the controller can execute the control logic of the moving driving mechanism according to the working state of the terminal device. For example, when the terminal device is powered on, the controller controls the moving driving mechanism 110 to drive the sound box assembly 120 to move from the non-working position to the working position. When the terminal device is powered off, the controller controls the moving driving mechanism 110 to drive the sound box assembly 120 to return from the working position to the non-working position.

[0103] The controller can output a moving control signal and a rotating moving control signal for controlling the operation of the moving driving mechanism 110 and the operation of the rotating driving mechanism 140, respectively.

[0104] The moving control signal can include a first GPIO (General-Purpose Input / Output) signal and a first PWM signal. The first GPIO signal is used to control the moving direction. For example, a high level of the first GPIO signal is used to trigger the moving driving mechanism to drive the speaker assembly to move from the non-working position to the working position. A low level of the first GPIO signal is used to trigger the moving driving mechanism to drive the speaker assembly to return from the working position to the non-working position. The first PWM signal is used to control the moving speed. For example, a duty ratio of the first PWM signal can be used to control the moving speed of the moving driving mechanism to drive the speaker assembly to move between the non-working position and the working position. The duty ratio of the first PWM signal can be positively correlated with the moving speed.

[0105] The rotating control signal can include a second GPIO signal and a second PWM signal. The second GPIO signal is used to control the rotating direction. For example, a low level of the second GPIO signal is used to control the rotating driving mechanism to drive the speaker assembly to rotate counterclockwise at the working position. A high level of the second GPIO signal is used to control the rotating driving mechanism to drive the speaker assembly to rotate clockwise at the working position. The second PWM signal is used to control the rotating speed. For example, a duty ratio of the second PWM signal can be used to control the rotating speed of the rotating driving mechanism to drive the speaker assembly to rotate at the working position. The duty ratio of the second PWM signal can be positively correlated with the rotating speed.

[0106] In this embodiment, the second GPIO signal is activated only when the speaker assembly is moved to the working position.

[0107] The controller can obtain the real-time rotating angle of the speaker assembly detected by the encoder, and dynamically adjust the duty ratio of the second PWM signal by comparing the rotating angle with a target rotating angle.

[0108] The mutual exclusion control mechanism of the above controller can ensure that the moving driving mechanism and the rotating driving mechanism do not work at the same time, thereby suppressing the risk of mechanical conflict and equipment damage caused by simultaneously driving the moving driving mechanism and the rotating driving mechanism. In addition, since the rotating driving mechanism is prohibited from driving the speaker assembly to rotate when the moving driving mechanism drives the speaker assembly to move, the speaker assembly will not rotate inside the terminal device body, so that the terminal device body does not need to reserve additional space for the rotation of the speaker assembly, thereby further reducing the space requirement inside the terminal device, and thus enabling the terminal device to provide better sound performance while maintaining a thin and light appearance.

[0109] In one embodiment, as Figure 3 andFigure 4 As shown, the sound box device further comprises a connecting mechanism 130, which comprises a linear transmission part 131 and a rotary transmission part 132. The linear transmission part 131 is fixedly connected with the moving driving mechanism 110, for transmitting linear motion force to drive the sound box assembly 120 to move linearly between the non-working position and the working position; the rotary transmission part 132 is drivingly connected with the rotary driving mechanism 140, for transmitting rotary force; when the sound box assembly 120 is in the working position, the rotary transmission part 132 can rotate relative to the linear transmission part 131 under the driving of the rotary driving mechanism 140, so as to drive the sound box assembly 120 to rotate.

[0110] When the sound box assembly 120 is driven by the linear transmission part 131 to move from the non-working position to the working position, the moving driving mechanism 110 stops working, at which time the rotary transmission part 132 enters a rotatable state. When the rotary driving mechanism 140 receives a rotary control signal sent by the controller, it drives the rotary transmission part 132 to rotate relative to the linear transmission part 131 which remains fixed, thereby driving the sound box assembly 120 connected with the rotary transmission part 132 to rotate, so as to realize dynamic adjustment of the sound radiation direction.

[0111] In this embodiment, by providing a connecting mechanism comprising a linear transmission part and a rotary transmission part which rotates relative to the linear transmission part 131, the linear movement function and the rotary function of the sound box assembly can be realized independently, which realizes the separation of the movement function and the rotary function, thus ensuring the stability of the movement process and the accuracy of the rotary control.

[0112] In one embodiment, as shown in Figures 4 to 6 The connecting mechanism 130 comprises a first connecting piece (not numbered in the figure) and a rotating shaft 133, which comprises a fixed shaft segment (not numbered in the figure) and a rotary shaft segment (not numbered in the figure). The fixed shaft segment is fixedly connected with the first connecting piece to form the linear transmission part 131; the rotary shaft segment is drivingly connected with the fixed shaft segment as the rotary transmission part 132.

[0113] The connection between the fixed shaft segment and the rotary shaft segment can adopt a bearing (e.g. a ball bearing) or a sliding fit structure, so as to ensure the stability and reliability of the rotary motion.

[0114] In this embodiment, by providing a rotating shaft structure comprising a fixed shaft segment and a rotary shaft segment, the linear transmission part and the rotary transmission part can be reliably connected and realize their respective movement functions, while ensuring the stability of the movement of the sound box assembly.

[0115] In one embodiment, as shown in Figure 4 The rotary driving mechanism 140 comprises a rotary driving motor 141.

[0116] The rotary driving motor 141 can be a stepper motor or a brushless direct current motor, etc. The stepper motor can provide precise angle control, and the brushless direct current motor can provide higher torque output.

[0117] The output shaft of the rotary driving motor 141 can transmit power to the rotary transmission part 132 through a set transmission mode to realize the rotary motion of the loudspeaker assembly 120.

[0118] In some examples, the output shaft of the rotary driving motor 141 is directly connected to the rotary transmission part 132 as a rotating shaft. In this way, the rotary transmission part 132 is driven to rotate synchronously by the rotation of the motor rotor, and the loudspeaker assembly 120 can be driven to rotate.

[0119] In some examples, the output shaft of the rotary driving motor 141 is fixedly connected to a transmission gear (not shown in the figure), which is engaged with an arc-shaped rack (not shown in the figure) arranged around the first axis, and the arc-shaped rack is fixedly connected to the rotary transmission part 132. Here, the first axis serves as the rotary axis of the loudspeaker assembly, and passes through the rotation center or pivot point of the rotary transmission part 132. When the rotary driving motor 141 drives the transmission gear to rotate, the arc-shaped rack can be driven to rotate around the first axis through gear-rack engagement transmission, thereby driving the rotary transmission part 132 to drive the loudspeaker assembly 120 to rotate, to realize the adjustment of the sound radiation direction of the loudspeaker assembly 120.

[0120] In some examples, the output shaft of the rotary driving motor 141 is fixedly connected to a worm (not shown in the figure), which engages to drive a worm gear (not shown in the figure) rotating around the first axis, and the worm gear is fixedly connected to the rotary transmission part 132. Through the worm gear transmission structure, the rotary motion of the rotary driving motor 141 is transmitted to the rotary transmission part, thereby driving the loudspeaker assembly to rotate around the first axis, to realize the adjustment of the sound radiation direction of the loudspeaker assembly.

[0121] In the embodiment, the above-mentioned various transmission modes can effectively transmit the power of the rotary driving motor 141 to the rotary transmission part 132, to realize the dynamic adjustment of the sound radiation direction of the loudspeaker assembly 120. It can be understood that the specific transmission mode between the output shaft of the rotary driving motor 141 and the rotary transmission part 132 can be flexibly set according to the spatial layout and performance requirements in the terminal device body, and the embodiment does not make specific limitations.

[0122] In one embodiment, as shown in Figure 4 the rotary driving mechanism 140 further includes a motor mounting seat 142 fixedly connected to the linear transmission part 131. The motor mounting seat 142 is used to install the rotary driving motor 141.

[0123] The rotating driving motor 141 can be fixed in the motor mounting seat 142 by screw connection, buckle connection or welding, so as to keep the position stable during operation. The fixed connection mode between the motor mounting seat and the linear transmission part can be screw connection.

[0124] Since the linear transmission part 131 remains stationary during the rotation of the sound box assembly 120, the motor mounting seat 142 connected with the linear transmission part 131 also remains stationary, thereby ensuring the stable fixation of the stator part of the rotating driving motor 141 and avoiding the vibration or displacement of the rotating driving motor 141 during the driving of the rotating transmission part 132. In this way, the mechanical rigidity of the rotating driving mechanism is improved, and the stability of driving the sound box assembly to rotate is further improved.

[0125] In one embodiment, as shown in Figure 4 the moving driving mechanism 110 includes a moving driving motor 111 and a linear conversion assembly 112; the linear conversion assembly 112 includes a transmission screw rod, a nut and a second connecting piece. One end of the transmission screw rod is fixedly connected with the output shaft of the moving driving motor; the nut is sleeved on the transmission screw rod and threadedly cooperates with the transmission screw rod, so that when the moving driving motor drives the transmission screw rod to rotate, the nut moves linearly along the axial direction of the transmission screw rod; the second connecting piece is fixedly connected with the nut and fixedly connected with the linear transmission part.

[0126] When the moving driving motor 111 is started, the output shaft of the moving driving motor 111 drives the transmission screw rod to rotate. Since the nut is sleeved on the transmission screw rod and threadedly cooperates with the transmission screw rod, the nut moves linearly along the axial direction of the transmission screw rod under the thread engagement, converting the rotary motion into linear motion force. The linear motion force is transmitted to the linear transmission part 131 through the second connecting piece, driving the sound box assembly 120 to perform the extension or retraction displacement relative to the terminal device body, and realizing the movement between the non-working position and the working position.

[0127] In this embodiment, the screw-nut transmission mode is adopted to convert the rotary motion of the motor into linear motion, thereby driving the sound box assembly to realize smooth extension and retraction motion in the limited space inside the terminal device body, which helps to improve the stability of the movement of the sound box assembly between the non-working position and the working position.

[0128] In one embodiment, as shown in Figure 4 the sound box device further includes a reinforcing member 150. The reinforcing member 150 is connected between the rotating transmission part 132 and the sound box assembly 120.

[0129] In some examples, the reinforcing member 150 is formed in an integral structure, for example, the reinforcing member is made by metal stamping. The reinforcing member 150 includes a first side plate (not numbered in the figure) and a second side plate (not numbered in the figure) formed integrally. The first side plate is provided with a first groove 151, which is matched with the plate-shaped structure extending from the rotary transmission part body of the rotary transmission part 132. The sound box assembly 120 is correspondingly provided with a second groove 121. In the assembly process, the first groove 151 of the reinforcing member 150 is first embedded in the second groove 121 of the sound box assembly 120, so that the two form a superimposed nested structure; then, the plate-shaped structure of the rotary transmission part 132 is embedded in the first groove 151 of the reinforcing member, and is fixedly connected by a fastener (for example, a bolt). In this way, the rotary transmission part, the first groove and the second groove are multi-layered matched to form a stable mechanical connection.

[0130] In the embodiment, by arranging the reinforcing member to connect between the rotary transmission part and the sound box assembly, the connection stiffness between the connection mechanism and the sound box assembly can be improved, and the sound box assembly can be prevented from cracking.

[0131] In one embodiment, as shown in Figure 1 and Figure 5 , the sound box device includes two groups of driving mechanisms arranged symmetrically with respect to the sound box assembly, and different groups of the driving mechanisms are connected to different ends of the sound box assembly in the length direction; each group of driving mechanisms includes a rotary driving mechanism 140 and a moving driving mechanism 110.

[0132] Each group of driving mechanisms can be connected to the corresponding end of the sound box assembly 120 in the length direction through an independent connection mechanism (i.e., the sound box device includes two connection mechanisms 130), so as to realize synchronous driving of the sound box assembly 120 to move, so that the sound box assembly 120 is more balanced in force during movement, which helps to improve the stability of the movement of the sound box assembly 120.

[0133] The two groups of driving mechanisms are electrically connected to the controller, the moving driving mechanisms in the two groups of driving mechanisms are synchronously operated under the control of the controller, and the sound box assembly is driven to move linearly, the rotary driving mechanisms in the two groups of driving mechanisms are synchronously operated under the control of the controller, and the sound box assembly is driven to rotate around an axis parallel to the length direction of the sound box assembly, so that through the cooperative control of the controller, the sound box assembly can be ensured to be balanced in force during movement, and the stability of the movement of the sound box assembly can be improved.

[0134] In some examples, the controller can control the synchronous operation of the two groups of driving mechanisms through the respective state detection results of the two groups of driving mechanisms.

[0135] For example, the controller can dynamically adjust the driving parameters by comparing the state detection results of the two sets of driving mechanisms in real time, so as to eliminate the synchronization error of the two sets of driving mechanisms. The state detection result is a motor state parameter representing the rotation driving mechanism, and the motor state parameter includes one or more of the movement position of the sound box assembly in the rotation driving motor in the rotation driving mechanism, the rotation angle and speed of the rotation driving motor in the rotation driving mechanism.

[0136] In this embodiment, by arranging the two sets of driving mechanisms symmetrically relative to the sound box assembly and connecting to different ends of the sound box assembly in the length direction, the stress of the sound box assembly during movement and rotation is more balanced, thereby improving the stability of the movement of the sound box assembly.

[0137] In one embodiment, as shown in Figure 7 The sound box device further includes a first motor driving circuit 170 and a second motor driving circuit 180; the first motor driving circuit 170 is electrically connected with the movement driving mechanism 110 and is used to drive the movement driving mechanism 110 to work, so as to drive the sound box assembly to move linearly between the non-working position and the working position; the second motor driving circuit 180 is electrically connected with the rotation driving mechanism 140 and is used to drive the rotation driving mechanism 140 to work, so as to drive the sound box assembly in the working position to perform the rotation movement; the controller 160 is further used to send control signals to the first motor driving circuit 170 and the second motor driving circuit 180 respectively, so that the rotation driving mechanism 140 and the movement driving mechanism 110 are prohibited from working at the same time.

[0138] The first motor driving circuit can convert the movement control signal from the controller into a movement driving signal to drive the movement driving mechanism to work, so as to drive the sound box assembly to move linearly between the non-working position and the working position. The second motor driving circuit can convert the rotation control signal from the controller into a rotation driving signal to drive the rotation driving mechanism to work, so as to drive the sound box assembly in the working position to perform the rotation movement.

[0139] The first motor driving circuit and the second motor driving circuit can both adopt a motor driving chip or a Darlington tube. The motor driving chip can be an H-bridge driving chip or a stepping motor driving chip, etc., to ensure the stability and reliability of the driving process. The Darlington tube can control the large collector current required by the motor with a very small base current.

[0140] The controller sends control signals to the first motor driving circuit and the second motor driving circuit respectively to coordinate the working states of the two driving circuits, so as to ensure that the first motor driving circuit and the second motor driving circuit do not work at the same time, thereby realizing the mutual exclusion of the movement driving mechanism and the rotation driving mechanism, so as to avoid mechanical conflict and equipment damage risk, thereby improving the safety of the movement of the sound box assembly.

[0141] In one embodiment, as shown in Figure 7 The state detection circuit 190 is configured to detect motor state parameters, including one or more of a position of the movement driving motor in the movement driving mechanism 110, a rotation angle and a speed of the rotation driving motor in the rotation driving mechanism 140, and feed back corresponding state detection results to the controller 160. The controller 160 is further configured to control the operation of the rotation driving motor and / or the operation of the movement driving motor based on the state detection results.

[0142] The state detection circuit is electrically connected to the movement driving motor in the movement driving mechanism and the rotation driving motor in the rotation driving mechanism, and can collect various state parameters including the motor position, the rotation angle and the speed. The state detection circuit converts the collected state parameters into electrical signals and feeds back to the controller in real time. After receiving the state detection results, the controller can determine the current state of the sound box assembly. For example, when the sound box assembly moves from the non-working position to the working position, the controller can determine whether the sound box assembly is at the working position and whether the rotation angle of the sound box assembly reaches the target rotation angle based on the rotation angle of the movement driving motor.

[0143] In some examples, the state detection circuit can include a linear encoder arranged on an output shaft of the movement driving motor for detecting the position of the movement driving motor, and / or a rotation encoder arranged on a rotating shaft of the rotation driving motor for detecting the rotation angle and the speed of the rotation driving motor.

[0144] Based on the state detection results, the controller can control the operation of the rotation driving motor and / or the operation of the movement driving motor. For example, during the movement of the sound box assembly, the controller can control the first motor driving circuit to adjust the motor rotation speed of the movement driving motor. During the rotation of the sound box assembly, the controller can control the second motor driving circuit to adjust the motor rotation speed of the rotation driving motor. In addition, when the state detection circuit feeds back that the movement driving motor has accurately reached the working position, the controller will start the rotation driving mechanism, ensuring that the movement driving mechanism and the rotation driving mechanism work in an exclusive manner, effectively avoiding mechanical conflicts.

[0145] In this embodiment, by introducing the detection and feedback mechanism for the motor state, closed-loop control can be achieved. Through closed-loop control, the controller can accurately control the movement of the sound box assembly, improving the reliability and accuracy of the movement of the sound box assembly.

[0146] In one embodiment, the state detection circuit includes a photoelectric switch and an encoder. The photoelectric switch is configured to detect the position of the movement driving motor. The encoder is connected to the rotation driving mechanism and is configured to detect at least one of the rotation angle and the speed of the rotation driving motor.

[0147] Exemplarily, the photoelectric switch may be a reflective photoelectric switch or a through-beam photoelectric switch.

[0148] The photoelectric switch may be a photoelectric switch array, so that the position of the motor can be detected by photoelectric switches arranged at different positions.

[0149] For example, the photoelectric switch includes a first photoelectric switch disposed at a first fixed position on a device frame, the first photoelectric switch corresponding to a working position. When the linear transmission unit driven by the mobile drive motor reaches the first fixed position, the first photoelectric switch is triggered to generate a first level jump signal. The first level jump signal indicates that the speaker assembly driven by the linear transmission unit has reached the preset working position.

[0150] The photoelectric switch may further include a second photoelectric switch disposed at a second fixed position on the device frame, the second photoelectric switch corresponding to a non-operating position. When the linear transmission unit driven by the mobile drive motor reaches the second fixed position, the second photoelectric switch is triggered to generate a second level jump signal. The second level jump signal indicates that the speaker assembly driven by the linear transmission unit has reached the preset non-operating position.

[0151] The controller allows the rotation function of the rotary drive mechanism to be started only after determining that the speaker assembly has reached the working position based on the motor position signal fed back by the photoelectric switch.

[0152] The encoder is mechanically connected to the output of the rotary drive motor and is used to monitor its rotation angle and speed parameters in real time. In some examples, the encoder can be directly mounted on the end of the rotary drive motor's shaft, capturing subtle changes in rotational motion through a high-precision sensing mechanism.

[0153] Based on optical, magnetic, or capacitive sensing principles, the encoder precisely converts the rotational motion of the rotary drive motor's output shaft into electrical signals, including a pulse count signal representing the rotation angle and a frequency signal reflecting the rotation speed. This electrical signal is then fed back to the controller, enabling the controller to obtain real-time information on the actual operating status of the rotary drive motor, thereby achieving precise closed-loop control of the speaker assembly's rotational motion. For example, during the speaker assembly's rotation, the controller adjusts the PWM drive signal in real time based on the electrical signal fed back by the encoder to ensure a stable rotation speed and accurate rotation angle.

[0154] In this embodiment, the combined use of the photoelectric switch and the encoder enables comprehensive monitoring of the motion state of the speaker assembly, which helps to achieve high-precision control of the motion position and speed of the speaker device.

[0155] Next, combine Figures 8 to 10 , taking a TV speaker as an example, the speaker device provided in this application is further explained.

The circuit control system of the television sound box extension and retraction function extends the television sound box outside the television shell.

The circuit control system of the television sound box extension and retraction function extends the television sound box outside the television shell. Figure 10 As shown in the figure, the MCU as a controller controls the motor driving chip through the GPIO interface to drive the motor to rotate, the motor rotation drives the screw to rotate and pushes the nut to move, thereby generating linear motion power, so as to realize the function of the television sound box extension and retraction; the MCU adjusts the motor speed through the PWM signal, so as to realize the control of the motor speed; the position of the motor is detected through the feedback signal of the photoelectric switch, so as to realize the motion position control of the motor. The circuit control system of the television sound box extension and retraction function extends the television sound box outside the television shell.

[0159] In one embodiment, the sound box device further comprises a position sensor (not shown in the figure). The position sensor is used to perceive the current position of the user and feed back the position perception information to the controller; the controller is further used to control the rotation driving mechanism based on the position perception information to adjust the rotation angle of the sound box assembly, so that the sound radiation direction is directed to the current position of the user.

[0160] The position sensor can include an infrared detector and / or a depth camera, and the infrared detector can include an infrared array detector and / or an infrared structured light sensor.

[0161] When the current position of the user (for example, the user is a television viewer) changes, the position sensor can detect the change in real time and transmit the position perception information to the controller. The controller determines the current position information of the user according to the position perception information, generates a target rotation angle based on the current position information of the user, controls the rotation driving mechanism to work, so that the sound radiation direction is always directed to the current position of the user, thereby realizing the intelligent adjustment of the sound radiation direction.

[0162] Exemplarily, the user current position information can include a horizontal distance d1 of the user current position deviating from an axis in the terminal device screen and a straight line distance d2 of the user from the center of the terminal device screen. The controller can calculate the target rotation angle a based on the user current position information and a trigonometric function formula. The trigonometric function formula can be: a=k*arctan(d1 / d2), and k can be a preset coefficient, for example, k can be set to a value range of 0.8 to 1.2.

[0163] After the sound box assembly moves to the working position, the controller generates and outputs a rotation control signal to adjust the operating parameters of the rotation driving mechanism, so that the sound box assembly in the working position rotates from the initial angle to the target angle, and the accurate adjustment of the sound radiation direction is realized.
